GAGE FOR SAWS.

SPECIFICATION forming part of. Letters Patent No. 449,785, dated April'7, 1891.

Application filed June 13, 1890- Serial No. 355,325. (No modelJfollowing is a full, clear, and exact description, reference being hadto the accompanying drawings, forming a part of this specification, inexplaining its nature.

It is often desirable to gage in advance the depth of a saw-cut. Toenable this to be accomplished, I have devised a simple gage adapted tobe secured or attached to the sawblade at any desired angle in relationto and distance from the teeth of the saw.

Referring to the drawings, Figure 1 is a View in perspective of a sawpartially embedded in a block of wood, showing portions of the mechanismfor securing the gage to the saw. Fig. 2 is a view in side elevation ofthe block and saw, also showing the gage. Fig. 3 is a View in verticalsection upon the line on a" of Fig. 2. Fig. 4 is a View in perspectiveof. the gage removed from the saw. Fig. 5 is a view in perspective of aclamp, with the opening for the saw-blade somewhat enlarged to receivethe edge of a back-saw.

In the drawings, a represents the saw, and a the gage. It is preferablymade of metal, quite long and narrow, has the fiat under surface a therounded, curved, or inclined ends a and the rods a Each rod carries aclamp a which is movable lengthwise the rod, the clamp having a hole a",through which the rod passes. The clampis fastened in any desiredposition upon the rod by the screw a Each clamp also has a recess a inwidth of about the width of the saw-blade. This recess is located at adistance from the hole a to bring the saw-blade when inserted thereinparallel with the rod, and so that the inner side of the gage restsagainst the side of the saw-blade. (See Fig. 3.) Each clamp-block a isfastened to the saw-blade by a fasteningscrew a". 'Of course the Widthof the recess a may be varied to take saw-blades which vary inthickness. The rods a have screwthreads at their lower ends, and thegage has threaded holes into which the threaded ends of the rods screw.

It will be seen that the gage is very simple in construction, veryreadily applied to the saw-blades, and very easily adjusted.

Itis desirable that the gage have a relatively broad bearing-surface inorder that it may not scar or mark the surface upon which it is broughtinto contact by the saw. As the gage-bar is made of metal, it isdesirable that it should be light to secure a sufficient thickness ofmetal to properly receive the removable rods a and I have formed uponthe upper surface of the gage-bar the upward proj ections c. Thisincreases the thickness of the metal at these points and enables me toform in the gage-bar a threaded hole of sufficient extent to properlyreceive and hold the threaded ends of the rods a Having thus fullydescribed my invention, I claim and desire to secure by Letters Patentof the United States-- As an improved article of manufacture, a saw-gagecomprising a gage-bar to, having a broad bearing-surface, and theprojections 0 upon its upper surface in which are threaded holes, thestraight rods 00*, having threaded ends which screwinto the threadedholes into the projections c, the clamps a each of which has asaw-receiving recess a and fasteningscrew a", and the hole a removed orseparated from the recess a to receive one of the straight rods c and afastening-screw a substantially as described.
